Tire Pressure Ratings printed on the side of tires usually say MAX on the

These tires say "MAX Load 6175 lbs single at 110 psi cold"

So basically all that tells me is that it's ok for the tires to be inflated to 110 psi cold. I called Swift Onroad and they told me I should have ALL the tires inflated to 110 psi. That doesn't sound right. I was reading this article, which basically says what Tractor Man said: "Dump the Thump"

Here's a quote:

SET STEER TIRE PRESSURE at 110 psi on a 12,000-pound front axle.

SET DRIVE AND TRAILER TIRE PRESSURE within a broader allowable range. The legal load rating is only 75 psi for those tires. Most truckers settle between 85 psi and 105 psi, with 95 psi being the most common. Those pressures are well above legal load settings.

DON’T OVERCOMPENSATE FOR TEMPERATURE. Changes in temperature rarely create a problem for properly inflated tires. A 30-degree drop typically will cause only a 2-psi drop in tire pressure. If starting a trip in Miami where it’s 80 degrees and heading to Minnesota where it’s 10 below zero, the 6-psi loss is not an issue when beginning at a good inflation level.

When I checked my pressures this morning (outside temp was 0º F), all my tires including my steers were between 85 and 90 (one or two of the drives were around 100 psi for some reason). Now the trailer tires are about 90 and my steers about 100. So my steers are still a little low, right?

I seem to remember reading a discussion on this topic. Can't remember of it was here. But IIRC the conclusion was yeah, you could be screwed if an inspector wanted to be strict about it. But I'd imagine that the tire would heat up pretty quickly, so it probably doesn't come up very often.
